Subject: analyzer: Change cast from long to intptr_t [PR96608]

analyzer: Change cast from long to intptr_t [PR96608]

Casting to intptr_t states the intent of an integer to pointer cast
more clearly and ensures that the cast causes no loss of precision on
any platforms. LLP64 platforms eg. have a long value of 4 bytes and
pointer values of 8 bytes which may even cause compiler errors.

	PR analyzer/96608
	* store.h (hash): Cast to intptr_t instead of long
